Out of DATA at line 100 You will notice that line 50 usees the RESTORE statement to set the data ‘pointer’ to either line 170 where BL data is stored or to line 270 where Lotus data is stored. This ensures that data is read from the correct list. Lines 90 to 130 attempt to read off eight sets of data from the data lists, but fail when Lotus data is selected as only three sets of data are provided. The message Out of DATA at line 100 indicates the failure to find enough entries in the data table. Methods of overcoming the problem are given in chapter 27 which deals with error handling.
